Predicting risk-adjusted incidence rates of methicillin-resistant Staphylococcus Aureus and Pseudomonas Aeruginosa in cystic fibrosis programs in the United States.

BACKGROUND: Healthcare-associated transmission of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa occurs for people with cystic fibrosis (CF), but CF programs lack a process to monitor incidence rates (IRs). We assessed predictors of incident infections and created a model to determine risk-adjusted IRs for CF programs. METHODS: Using the CF Foundation Patient Registry data for all patients from 2012 to 2015, coefficients for variables that predicted IRs were estimated. Hazard functions were then used to predict IRs of MRSA and P. aeruginosa for CF programs based on their patient and program characteristics. Predicted IRs were compared with observed IRs over multiple time intervals. RESULTS: Multiple patient and program characteristics were identified as predictors of observed IRs. Our model's predicted IRs closely aligned with observed IRs for most CF programs. Alarm values (defined as observed IR > 95% confidence interval of predicted IR) were found at 5.9%, 5.9%, 6.0% (adult, pediatric, affiliate) of programs for MRSA and 3.0%, 1.7%, 0.0% (adult, pediatric, affiliate) of programs for P. aeruginosa. CONCLUSIONS: We found patient and program characteristics that predicted MRSA and P. aeruginosa IRs. Our model accurately predicted risk-adjusted IRs of MRSA and P. aeruginosa. CF programs could use our model to monitor their IRs and potentially improve infection prevention and control.

Barriers implementing infection prevention and control experienced by healthcare workers, people with CF and parents.

BACKGROUND: Barriers to implementing infection prevention and control (IP&C) practices may be experienced by healthcare workers (HCWs) caring for people with CF (PwCF), PwCF, and their families. We hypothesized that these stakeholders from CF centers with early adoption of the updated 2013 IP&C guideline would experience fewer barriers implementing selected recommendations compared to stakeholders from CF centers with delayed adoption. METHODS: In 2018-2019 we surveyed HCWs and PwCF/parents from 25 CF centers to identify knowledge, attitude, and practice barriers. Each center recruited five HCWs with different occupations. Pediatric centers recruited five parents of children <18 years old and five young adults 18-21 years old. Adult centers recruited 10 adults ≥18 years old. We determined respondents' knowledge scores, the proportion who agreed with or perceived health benefits from recommendations, and reported adherence to recommendations. RESULTS: Knowledge scores, perception of health benefits, and adherence to selected practices were similar among participants from centers with early vs. delayed adoption, yet generally lower for inpatient nurses. IP&C practitioners were less likely to perceive health benefits from PwCF wearing masks and HCWs wearing gowns and gloves. Among HCWs, 57% educated >75% of PwCF/parents about IP&C and 43% advised >75% of PwCF/parents to avoid socializing with other PwCF. Among PwCF/parents, 69%, 53%, and 56% reported discussions with their care teams about performing hand hygiene, avoiding socialization, or the 2013 IP&C guideline, respectively. CONCLUSIONS: Our findings suggest opportunities for targeted education for specific HCW occupations and for PwCF and their families.

Cystic fibrosis program characteristics associated with adoption of 2013 infection prevention and control recommendations.

BACKGROUND: The Cystic Fibrosis (CF) Foundation disseminated an updated guideline for infection prevention and control (IP&C) practices for CF care programs in 2013. Assessing adoption rates of IP&C recommendations is crucial to evaluate their impact. METHODS: CF care programs provided their written IP&C policies for CF. Policies were analyzed to determine adoption of selected recommendations new in 2013, as well as recommendations made in both 2003 and 2013. Weighted adoption scores were analyzed for association with program characteristics. RESULTS: The median number of new recommendations adopted by each program was 7 (mean 6.3, range 0-9). The most commonly adopted new recommendations were universal mask use by patients in both inpatient and outpatient settings (85% and 87%, respectively) and contact precautions for CF patients in inpatient and outpatient settings (90% for both). The least frequently adopted new recommendations were the "6-foot rule" in inpatient settings (n = 66, 53%) and auditing disinfection of surfaces in clinic (n = 64, 49%). Larger program size was associated with a higher weighted adoption score (odds ratio [OR] 1.9, P =.02). CONCLUSIONS: Whereas most programs adopted more than one-half of the selected IP&C recommendations assessed, adoption was variable. Efforts to improve adoption of IP&C recommendations should focus on smaller programs with fewer resources.

Improving Timeliness of ß-Agonist and Corticosteroid Administration in Patients With Acute Wheezing.

OBJECTIVE: Timely delivery of ß-agonists and steroids to patients with acute recurrent wheezing is a key component of the National Heart, Lung, and Blood Institute recommended emergency department (ED) asthma care. We conducted an ED improvement initiative to standardize asthma care and improve time to treatments. METHODS: Our multidisciplinary team identified key contributing factors to timeliness, developed key driver diagrams, implemented and refined a management pathway, designed and executed rapid cycle improvements, and implemented interventions. A time series design was used to analyze outcomes with baseline data and continuous monitoring during active intervention steps. The primary outcomes analyzed were the times to first ß-agonist and steroid administration. Secondary outcomes included admission rate, ED length of stay, and ED revisits. RESULTS: Assignment of the Pediatric Asthma Score, our initial pathway step, occurred in most patients within the first several months. Time to first ß-agonist administration decreased from the baseline mean of 76 minutes to 27 minutes. Time to steroid administration decreased from the baseline mean of 108 minutes to 49 minutes. Mean monthly admission rate remained at 22% with no special cause variation identified. The ED revisit rate was not negatively impacted and, in most months, was 0%. CONCLUSIONS: By standardizing asthma care in our ED and redesigning care delivery processes, care variation decreased and significant improvements in timeliness of ß-agonist and steroid administration occurred.
